Metal ground against metal; a lurching shudder shook the floor beneath him. He fell down at the sudden movement and shuffled backward on his hands and feet, drops of sweat beading on his forehead despite the cool air. His back struck a hard metal wall; he slid along it until he hit the corner of the room. Sinking to the floor, he pulled his legs up tight against his body, hoping his eyes would adjust to the darkness.
